A Liquid Crystal Display (LCD) includes: a liquid crystal panel having liquid crystal cells divided by scan lines and data lines and arranged in a matrix shape; a data driving circuit to supply an image signal to the liquid crystal cells via the data lines; a scan driving circuit to sequentially select and scan the scan lines and to control an on/off state of switching elements arranged in each of the liquid crystal cells; a timing controller to drive both the data driving circuit and the scan driving circuit, based on an externally inputted signal; and a common electrode driving circuit to drive a common electrode of the liquid crystal panel. The common electrode driving circuit supplies a common voltage to the common electrode, the common voltage including a DC voltage for a first period of a first horizontal period (1H) and another voltage for a second remaining period of the first horizontal period (1H).
